What Does a Home Warranty Actually Cover?
Home warranties cover breakdowns from normal wear and tear on major systems and appliances. This guide explains everything in simple terms so you can see exactly what’s included, what’s optional, and what’s excluded across almost every company.
Key idea: A home warranty is designed to reduce the cost of repairing
or replacing covered systems and appliances — not damage from storms, flooding, or fires.
